Some minor diagnosis and questions.

[Auladan]

I recently got my car running again after having the ECU repaired, but, being a DSM, I'm sure she has something devious planned for me soon.

So I was just out snooping around her inards looking for an oil leak I was already aware of. The driverside of the crankcase (the part I can see with the car on the ground and all, which is mostly the oil pump) is wet with oil. There's also oil on the front crossmember (that's what that frame rail just below the radiator is called, right?) is wet with oil, as well as just under the built in feed line on the head for the turbo's oil, but not at the junction of the actual feed line (which I repaired due to a previous leak).

So I turned the car on to look for any visible oil seepage while she idled and didn't find any, but I did hear from under the valve cover some ticking I havn't heard before. It's quiet, but it's there. Is this lifter tick? I bought this motor used from Japan (all I could afford) a year ago, but I've only had it running several months at most.

Going back to the oil leak at the turbo oil feed line that I prevoiusly fixed: The aluminum threads were torn off in to the bolt that held the feed line in place somehow, and the leak became so bad that one day on my way home from school I went through two jugs (don't know how much of oil in each, but they were big jugs) of oil. It was literally spraying oil out in my bay. At one point, the car even shut off. I feared the worst (siezed motor or what not) but after filling it with the last of the oil I had, she got me home fine. We fixed it a day or so later, and havn't had any leakage from there. Could this be responsible for the ticking I'm hearing?

Any aid would be wonderful, thank you.

(EDIT: I don't know why I didn't think of it, but the ticking may very well be my injectors. Heh. Still, if anyone has ideas or thoughts about where the oil leaks are most likely coming from, or what kind of damage could have been caused by that massive oil leak I explained, I'd appreciate it)

Do you still have your 90 oil cooler?

Yes. The JDM motor is year 91+ so I had to change some wiring and the like around, but everything else off the motor is still '90.

One of the common fixes for the banjo bolt is to buy the oil line replacemet kit that uses a braided line from the oil filter to the head. If the outermost head threads are damaged you might have to buy a larger fitting after re-taping the hole larger and then reduce back to the correct hole size. Should you try to make your own do maintain the same inside diameter for it's metered to reduce cam pressure around 25 psi. If you have to drill and tap please follow common shop practices for keeping chips out of the oil passages.

Were you out on the road and had to make emergency repairs you could cut the banjo fitting off and then use high pressure fuel hose and a hose barb to fit the banjo bolt hole.

I suspect that some of the vendors here on DSMtuners will have this kit.

Cheers,

Then check for leaks there, it's infront of the radiator.
